Heya! I'm not entirely sure if this is implemented within the game, but is it possible that the amount of population within the village be coorelated with the amount of taxes there are as well as rent from castles for the Population? It would make having a fief in general more rewarding when you start to build it up gaining more advantage rather then just having more boosts of soldiers and that be it. I'm not entirely sure if it alrdy had been implemented but if not, I feel it would be a great idea to put into the shoebox!
